fatal: Out of memory, malloc failed error on git pull on Ubuntu VM

I ran git pull on my Ubuntu VM, and I got

As you can see at the end - it pull in my local changes fine.

But I just want to get rid of those errors, how do I get rid of them? Clear my cache?

I saw git gc is the recommended command to clean local files, but I can't even run that.

I also tried

Finally, run git pull one more time got this

Your RAM size may will be lower, you have to Add Swap Space. I had done it in ubuntu 16.04 and solved this issue

The below code displays if swap 

free -h

if swap is zero then check there is enough memory to add the swap

df -h

My RAM is 1 GB so allocating 1GB to swap space also

sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon --show

This will display something like this, then success

NAME      TYPE  SIZE USED PRIO
/swapfile file 1024M   0B   -1

Thanks

Try following the instructions here: https://stackoverflow.com/a/8761464/1278288

git config --global pack.windowMemory "100m" git config --global pack.packSizeLimit "100m" git config --global pack.threads "1"

It should reduce the memory needed.

It's a good idea to have at least 1gb of swap though.

Well, your system is simply out of RAM. Git regularly runs git gc if needed and that is where the error message comes from as you also can see when running it manually. It tries to repack your Git repository and it fails when trying to allocate 293 MiB additional RAM. Put more RAM into your box or at least enlarge the swap size, even if only temporary to make the repack finish successfully. You can easily add some swap file while the system is running if you only want to make this temporarily to help the repack to finish. Documentation can be found at https://help.ubuntu.com/community/SwapFaq#Four-step_Process_to_Add_Swap_File without doing the last step if only temporary.
